Transfer large data using WCF

Hi,

My requirement is to transfer data to a client through WCF services. Data can be of 1MB to 1GB size to be transferred.
So, what can I do, I can pull Data from the database and provided to the client through WCF service.Client can then add it in its local database. How can I manage transferring large data? I want to be able to resume the process if it fails in the middle of the transfer. How can I know if the Client local database has been updated or not.Should I be using a WCF streaming?

Thanks.

Just wanted to know if ReplyAction attibute can be used instead of CallbackContracts for ensuring that the data has been received at the Client end. What is the difference between CallbackContracts and ReplyAction.

hi,
To transfer large amount of data you have to some change in web config and this will enable you WCF to transfer large data.


                            maxBufferSize="2147483647"
                maxReceivedMessageSize="2147483647">

Hi,

The best options to use Streaming.

Streaming is explained here in MSDN.

For "How can I know if the Client local database has been updated or not",

You can use CallbackContracts.
